Abstract | Purpose Epithelial-mesenchymal transition (EMT) in cancer is
characterized by altered cell morphology, weakened cell-cell adhesion, and increased tumor invasiveness. Cytoskeleton protein
dysregulation enhances EMT but its translational significance in
the pathogenesis of glioblastoma multiforme (GBM), a highly
invasive form of malignant brain tumor, is not known. Adducin 3
(ADD3) is a major cytoskeleton protein in glioma cells. Our preliminary studies revealed significant downregulation of ADD3
in GBM, and provided the first in vivo evidence on the putative
tumor suppressive role of ADD3 in modulating GBM growth
and angiogenesis. We aim to interrogate the translational potential of ADD3 as a therapeutic target and to unravel the molecular mechanisms underlying EMT induction in GBM. Methods
To better recapitulate the disease-relevant tumor environment,
GBM cells will be studied in an ECM-enriched culture system
in vitro and in animal-based models. Cells will be cultured and
maintained in fibronectin-coated plates. Results It was found
that ADD3 loss-of-function promote EMT phenotypes in GBM,
mediated through significant changes in cellular polarity, and the
focal adhesion signaling pathways that favors cancer cell migration and invasion. Conclusions The highly infiltrative behavior
of GBM is an important determinant that contributes to treatment
failure. It emerged that GBM is equipped to downregulate ADD3
at the genetic level to drive cytoskeletal changes that favors cell
proliferation and mesenchymal phenotype. Our study revealed
the molecular mechanisms on how cytoskeleton protein ADD3
renders GBM cells towards an EMT phenotype that drives cancer
cell invasion in GBM |
